Definitions

  • the invention relates to a blood collection tube in which an anticoagulant is enclosed.
  • This blood collection tube comprises a bottomed tube whose open end is hermetically sealed by a plug and a porous support having an anticoagulant such as heparin sodium carried thereon, accomodated in said bottomed tube.
  • the present invention is intended to carry a predetermined quantity of an anticoagulant on a support surely and easily, when the anticoagulant is carried on the support and charged in a tube.
  • a blood collection tube according to the invention described in claim 1 comprises a bottomed tube whose open end is hermetically sealed by a plug, and a supporting film having an anticoagulant coated thereon, accomodated in said bottomed tube, wherein an anticoagulant-coated surface of said supporting film has a large number of fine convexes.
  • the large number of said fine convexes are made such that 2 ⁇ 500 convexes with a height of 0.2 ⁇ m or more exist per a length of 1 mm, in the cross section of said film in the thickness direction.
  • the bottomed tube accomodates further a thixotropy gel having a specific gravity of 1.03 ⁇ 1.60, and the specific gravity of said film is made heavier than that of said gel.
  • heparin sodium or heparin lithium is used as said anticoagulant.
  • a surfactant is contained in said anticoagulant.
  • water-soluble silicone is used as said surfactant.
  • a blood collection tube 10 comprises a bottomed tube 12 whose open end is hermetically sealed by a plug 11, and a supporting film 13 having an anticoagulant coated thereon, accomodated in said bottomed tube 12.
  • the tube 12 is made of glass, plastic or the like.
  • the plug 11 is composed of a gas barrier member 11A and a sealing member 11B.
  • the gas barrier member 11A is made of an aluminium foil film or the like and is highly gas-tight before a hollow needle is pierced therein, and it closes the opening of the tube 12.
  • the sealing member 11B is made of polyisoprene rubber or the like, and it is applied at least on an area of the gas barrier member 11A where the hollow needle will be punctured, and enables to plug a hole left after the punctured hollow needle has been removed therefrom.
  • the supporting film 13 is made of polyethylene terephthalate film or the like, and subjected to an embossing treatment so as to have a large number of fine convexes on the anticoagulant-coated surface.
  • the embossing treatment for giving these fine convexes is carried out by polishing methods, such as a sandblast, a shotblast, a molding method using a die mold having concaves and convexes formed thereon, an emboss-printing method, a etching or the other methods.
  • the sandblast method is preferably used because of the adherence of the anticoagulant to the film and the stability of the anticoagulant.
  • Sands and glass beads or the like are preferably used in the sandblast method.
  • the roughness of the embossed surface is tested by the surface roughness gauge.
  • the grade of the large number of said fine convexes formed on the supporting film 13 is preferably made such that 2 ⁇ 500 convexes with a height of 0.2 ⁇ m or more exist per a length of 1 mm in the cross section of the supporting film in the thickness direction.
  • the anticoagulant can be surely carried on the supporting film 13, while it is not likely to be exfoliated therefrom.
  • the tube 12 accomodates a thixotropy gel 14 having a specific gravity of 1,03 ⁇ 1.60, and the specific gravity of the supporting film 13 is set to be heavier than that of said gel 14.
  • the thixotropy gel 14 is substantially hydrophobic and thixotropic, and is substantially inert to blood. It is necessary that the specific gravity of such thixotropy gel is medium between those of the blood-plasma component and blood-corpuscle component. It is preferably in an order of 1.03 ⁇ 1.035 which is lighter than that of the blood-platelet component.
  • the specific gravity of a blood-plasma component is often heaveir, varying with blood donors, and in such a case, the gel may get out of an intermediate position between the blood-plasma component and blood-corpuscle component. It is, therefore, preferred that the specific gravity of the gel is suitably selected between 1.03 ⁇ 1.06, for the purpose of use.
  • the gel when the blood collection tube 10 in which blood has been collected is set on a centrifuge, the gel exhibits a fluidity and immigrates to the border of the two components, and it provides a wall in a semi-solid state, i.e. in a non-flowable state which isolates the two components from each other, as centrifugal force is stopped.
  • the thixotrophy gel 14 for instance, there are used a gel consisting mainly of an ⁇ -olefin-maleic acid diester copolymer having a viscosity of 10,000 ⁇ 80,000 cp (25°C) or a gel consisting mainly of silicone in which a viscosity modifier, a spesific gravity regulator and the like are added.
  • the supporting film 13 Since the supporting film 13 has a specific gravity heavier than that of the thixotropy gel 14, it is not moved to the side of the blood-plasma component separated as mentioned above, and settles in the side of the blood-corpuscle component.
  • heparin sodium, heparin lithium or the like is used for the anticoagulant coated on the supporting film 13.
  • the coating quantity of the anticoagulant on the supporting film 13 is preferably as large as 20 ⁇ 100 units.
  • the anticoagulant is coated on the supporting film 13, in addition, it is dried by heat drying or freez-drying or the other drying method so as to be carried on the supporting film 13 in a more stable state, or without being exfoliated therefrom.
  • a surfactant is preferably contained.
  • water-soluble silicone is used for the surfactant.
  • the surfactant improves the wettability of the surface of the supporting film 13. Since the supporting film 13 is hydrophobic and the anticoagulant is hydrophilic, namely, the hydrophobic groups of the supporting film 13 and surfactant are attracting each other due to the hydrophobic interaction, and the hydrophilic groups of the anticoagulant and surfactant are attracting each other due to the hydrophilic interaction, and as a result, the anticoagulant can be surely carried on the supporting film 13.
  • a evacuated blood collection tube was manufactured in the same manner as Example 1, except that the embossing treatment was not carried out. After drying, however, heparin lithium was exfoliated from the supporting film so that the blood collection tube was useless.
